Prisma finally introduces full-resolution pictures
Prisma brings some much needed improvements to the art filter app. The 1,080 x 1,080 pixel square resolution limit is now gone so users are free to crop photos how they please and filtered images now have twice the resolution as before to get better-quality photos. There is also now a new location-based photo feed in the app to algorithmically show you nearby photos from other Prisma users. Those images that get more likes will be shown more. An interactive app is also visible in the app so you can show easy access to landmarks. The update is coming to Android and iOS. However, the free aspect ratio feature is currently only available to the iOS app.
